FLASH-HINGE.

Referring specilically to the drawing, 5 denotes the drag or lower halfof the flask; and

. 6, the `cope which is hinged. to the former so that the parts may. beseparated. The two hingemembers are indicated at' 7 and 8, renyspectively The hinge member 7 is secured to the drag, and comprises aplate 9 having slots-1() t0 receive the screws orother fastening means11 whereby the member'is securedto thev drag.

At the top of the plate is a forwardly extending ledge or shelf 12, the`top ofwhich has a socket 13.

The hinge member '8 comprises a plate V14 having holes to receive screwsor other -fas.-` tening means 15 whereby it is secured to thev cope. Atthe lower edge of the plate is a ball 1.6 which lies in the sockets13when the hinge members are assembled. The plate 14 has a strengtheningrib 17 which extends upwardly the ball. The top of the ledge has agtodve 18' which extends forwardly from the v specification f LettersPatent. Application filed August 23,

socket 13, and receives the rib 17 when the cope is swung outwardly. Theledge also has .a vertical opening 19` which communicates with thesocket so. that the sand which falls from the flaskmay work its way outfrom the hinge members.

The. hinge ,herein ldescribed is light and strong, and is particularlyadapted for keeping the shift out of the flask'when it isopened .andclosed. The ball will'not crawl out of the socket if the hinge is notput on straight, and Athe parts will always match.

The back of the plate 14 extends tangentially from the ball 16, andthere is no intermediate shank connecting the ball and plate, the latterbeing connected directly to .the ball. This arrangement brings the ballclose 4to the cope, and also renders it less-liable to be broken off inuse, and enables it to successfully withstand rough usage of the' flaskas when shaking out the sand, etc.

I claim A flask-hinge comprising a plate secured to the cope, andliavinga ball aty its lower edge, the back of said plate extending tangentiallyfrom the ball, and a socket member secured tothe drag, and adapted toreceive the ball.
